nfc_t4t_setup()

int nfc_t4t_setup	(	nfc_t4t_callback_t	callback,
		void *	context )

#include <nfc/include/nfc_t4t_lib.h>

Register the application callback for event signaling.

The callback will be called by NFCLib to notify the application of relevant events. It will be called from the HAL_NFC callback context. The library support 3 different Modes of Emulation:

• Raw ISO-Dep exchanges. All PDUs are signaled through the callback.
• Read-Only T4T NDEF-Tag. A static buffer is served. Only Field-Status callbacks.
• Read-Write T4T NDEF-Tag. A mutable buffer is used. Only Field-Status callbacks.

The default mode is Raw ISO-Dep mode. The two other NDEF T4T modes are activated through the corresponding nfc_t4t_ndef_rwpayload_set/ nfc_t4t_ndef_staticpayload_set functions. The mode is locked in with a call to nfc_t4t_emulation_start.

Parameters

callback	Function pointer to the callback.
context	Pointer to a memory area used by the callback for execution (optional).

Return values

0	Success.
-NRF_EINVAL	Invalid argument (e.g. wrong data length, NULL pointer))
-NRF_EOPNOTSUPP	If emulation is in running state.
